S'iORM-WVINDOWVFASTENER.

Application med March 7, 1927. serial No. 173,370.'

My invention relates to storm window fasteners, and has .for its object the provision ofV a device enabling the vmount-ing of storm windows from outsidethc building,v

The object of my invention is to contrive a fastener wherewith no tool is Vrequired to either mount or vdismount a window.

Tn the accompanying drawingsjrforming part of this specification-- i Figure 1 is a perspective' view 0f a fastener as applied to the window frame i Figure 2 is a perspective view of a 'portion of a storm window with a tongue attached;

Figure 3 is a side view of a fastener;.

Figure 4 is a facevicw thereof; A

Figure 5 is a sectional view through line 5 5, Figure 4;

Figure 6 is a sectional view of a portion of a fastener showing the tongue as engaged by the jaws of the fastener; Y

Figure 7 illustrates the shape of one of the guiding members for the .gripping j aws; and

Figure 8 illustrates the construction of the tongue to he fastenedto the storm sash.

The fastener comprises 'a casing of rec-l tangular form. vwhich may be made of one piece metal pressed to shape. One side of the'casing extends past the ends thereofand these extensions 9 are provided with perforations 10 to enable the mounting of the fastener upon the sido of a window frame. The back Y11 of the casing is maderemovable and is preferably fastened thereto by means of screws 12, the ends of the frame'projecting inwards suiiiciently lto provide threaded perforations 1.3 into which the screws 12 engage. A pair of guiding members 18 are mounted inside the sides 14 and 16';4v and to adjust them longitudinally in the casing, slots 16 are provided on both sides of the casing into which project rivets or bolts 17 which are fastened to the guiding members and retained by means of nuts to allow the adjustment of the members in the slots. The guiding members are shaped so as to direct the gripping jaws to open or close as the tongue enters in or is taken out therefrom. They are shaped with an inclined base 19 and a raised incline top portion 20, as well as a stop portion 31. Both ends of the casing are perforated to receive threaded tubes 21. Threaded rods 22 engage these tubes and springs 23 are mounted on the rods The carry at their inner ends .jaws 24 having inner serrated faces. These jaws are provided on each side with integral angular side lugs *25 intended totravel on the guiding members 1S.

In order to regulate the tension Vofthe springs 23, washers or discs 26 are mounted baclrof vthe springs betweenvthe ends thereof and the threadedrtubes y21. Over/thev threaded .tubes 21 spiraif springs 27 are end by the washers 26 and at the other end by resting against the ends of the casing,.- Tlie threaded tubes are providedv at their outer ends with slots 28 to enable the turning of the same by means of a screw-'driven' It will be noticed that the springs 23 andv 27 are of different diameter and that the guidiran STATES (PATE-Nr oF-Fics. fn ing members 'havethree different angles,A on

which the side lugs of the gripping Vvjaws travel. The object of the springs is to press the jaws against the guiding member with, an equal tension irrespective of their posi-- tion thereon. In order to obtain this result,` the spring 23 is counterbalanced'by spring 27 and compensates for the lengthening or shorteningof the rod 22; This is doneV in the following manner: If the threaded tube 21 is unscrewed, 'the spring 23 will be extended and spring 27 will be under a greater tension. If the tension on the spring 27 becomes too high, the washer 26 willmove on rod. 22 towards the gripping jaws to coun-V` terbalance thel springs, irrespective of the Alength of the rod.

It will be understood, ofcoursefthat the threadedtubes21,travels to and fro in the rends of therasing and that when the jawsY engage the tongue 30, they are at their innermost position; In order to retain the same in Athis position,v screws 29` are threaded in the ends of the casing adjacent the threaded tubes. One side of the head of the screws is taken Vofi' so that when turned against the tube it will not prevent the .saine vfromreciprocating; whilst if the head portion is turned on the end, they are'loclred in position.

The number of fasteners used varies according to the size of the storm window and may comprise one, two or three pairs.V They are mounted, as shown in Figurel 17 on opposite sides of the window frame and the storm'sash is provided with serrated tongues 8O having integral screws 32 to fasten the lsame to the sash. `These tongues are tioned on the sashss that the mounted. These springs .are retained. et one' 6.5

Vmounted in position, they willl enter the gripping jaws 24, thus holding the storm sash in position.

ln referring to Figure 5, it will be noticed that the jaws are'separated and held thus by the portion 31 of the guiding` member 1,8.

An aressure an alied on the O'ri )'in 'aws' l l r9 C 24: by the storm window will canse the jaws to be depressed, when they will be free from the retainingr portion '3l 4 and will slide against lthe portion of the guiding 1ne1nber 18, thusl allowing the closingl of the jaws K against the tongue 30.

In order to remove the storm window, allv that'is necessary is to pryv the same outwardly, when the grippingfjaws will slide against the portion 2O until it reaches the portion 31 of guiding meinberflf and thus remain in separated position and free the toiileujeSO- A The form of my fastener is one that in actual use has given satisfactory results, but it yshould be understood that fchanges maybeinade without ydeparting from the spirit of vmy invention as covered by the following claims: j Y Y l. ln a fastener' of the class described, a casing, jaws mounted centrally. of said casing; and slidable therein, guiding. means to direct the jaws in either opened or closed position, and pressure means back of said jaws `to maintain them4 under tension. y

,2. ln a fastener of the classV described, a frame of rectangular' form, an opening in one side of said frame, slots on the opposite sides thereof, guiding meansy adjustably mounted in said frame traveling in said slots, jaws mounted in said opening 'and pro-` vided with projections to travel on said guiding means, rods fastened to said jaws, springs mounted on said rods to maintain the same pressed against said guiding means, and. means to adjust the tension of said springs. j

Byln a fastener of the class described, a frame, an opening in one side of said frame, a pair4 of jaws mountedin said opening, a. pair of `gui/ding`- members one on each lside of said jaws adjustably mounted in said frame, rods fastened to 'said jaws extending bac-k tube, a tension spring mounted ove-r the threaded tube betweenA the ,easing and the inner end ofu said tube, pcrforations in said casing` to allow the threaded tube to travel f therein, Aand means on the vtube to adjust tlie springs according to the tension required.

fi. ln a fastener of the class described, a freine, an opening 1n vone side thereof, a pair of jaws travelling in said openin",

extensions on both sides of saidjaws, gint ing members adjustably mountedly one on each lside of said opening, positioned so that the extensions of the jaws will engage the saine, tension means back of'said jaws', and means to adjust the tensionof said tension means. j Y' 5. In a fastener of the class described, a casing` fof rectangular form, an opening` on oneV side of said casing, 'a pair of jaws mounted in said opening, extension rods integral with saidja-ws, perforations'at both ends of j y l rods to move longitudinally and vertically therein, springs mounted between said jaws and the inner to counterbalance the tension of said lsprings according to the position of said rods. v

6, In a fastener of the cla-ss described, a

casing of rectangular form, an opening onv one side thereof, a pair of jaws mounted ,1n

said opening and extending inside the casing, capable of moving vhorizontally or vertically, apair of guiding' members mounted one on each side of said jaws, projections on said jaws to travel ao'ainst the face of said guid ing members, serrations onv the inner ffice of said jaws, a tongue, serrations on said tongue corresponding tothe Serrat-ions ein the gripping jaws, and means on said tongue to 'fasten the same toa storm sash.

In testimony of the foregoing, .I have hereto affixed my signature., this 22nd dayV of i November, y1925, atl Campbellton the county of lRestigouehe ancl.Provinc`e offNew Brunswiok, Canada. Y r
